This isolated barrier is used for intrinsic safety applications. It
is a universal frequency converter that changes a digital input
(NAMUR sensor/mechanical contact) into a proportional free
adjustable 0/4 mA … 20 mA analog output and functions as a
switch amplifier and a trip alarm.
Also the functions of the switch outputs (2 relay outputs and
1 potential free transistor output) are easily adjustable [trip
value display (min/max alarm), serially switched output, pulse
divider output, error signal output].
The unit is easily programmed by the use of a keypad located
on the front of the unit or with the PACTware™ configuration
Line fault detection of the field circuit is indicated by a red LED
and through the collective error output via Power Rail.
